. Be it known that I, Fmnonn Conmscuonn,

a subject of the German Emperor, and a .rcsident ofFrankfort-on-the-Main, Germany, have invented certain new and usefulImprovements in Driving Mechanisms for Motor-Vehicles, of whichthefollowing is a specification. 4

This invention relates to improvements in driving .mechanisms for motorvehicles, and

more particularly in motor vehicles ofthat class in which powercan bedirectly trans mitted. from a driving member or prime mover to thewheels, or indirectly by means of a secondary mover'driven by said primemover and transmitting the power to the wheels. a

The object of'the improvements is to rowide a mechanism of this class inw ich consists in -provi'ding' a mechanism which consists of 'thecdmbination of a prime mover;

a single electric generator adapted be driven by said prime mover, aplurality of electrom'otors adapted to be dnven by the electric currentsupplied by the electric generator and to transmit power to the wheelsof the vehicles or driven member or mem,-

bers, means for coupling the prime mover and the drivingmechamsm for thewheels of the vehicle, and a difl'ferential caring ;connected with thesaid driven mem rs.

Forthe purpose of explaining the invention two examples embodying thesame have been shown in the accompanying drawing I niatical plan of t ua single electromotor, and F1g. 2, 1s a dia- --in' Wbich thesame letterreferences have been'usd in all'the views to indicate correspondinparts.

Tteferring particularly to the example illustrated in- Fig. 1 of thedrawing, the rime'mover, which maybe for example a nzinmoto'r, has beenindicated by the letron moron-V HICLES.

ter p. The said prime mover isconnected with the armature of a dynamoelectric genenter 9. In the preferred form a clutch h is interposedbetween the prime mover and the dynamo, which clutch may be constructedas a friction or sliding clutch. The electromotor has been indicated bythe letter m.- Its urmaturecan be connected to the armature of thedynamo by means "oil-m clutch k. In the drawing the field magnets of theelectrical machines, the'collectors and other subsidiary apparatus havenot been shown.

In the example shown in f the shaft 0f the armature of the electromotorm drives a pair of'sprocket wheels r and r through the mtermedmry of adiiferentil gearing d of .known construction, whidh sprocket -Intmounted 0n shaftgfcf .the driven wheels 1 and'r respectively and whichare connected to gears a and?) of thedifierential gearing wheels areconnected by chains to the wheels v of the vehicle as is common ;in'vehicles of f .7

y e emmpleillustrated in Fig 2 two electromotors m and m are used whichare The planet gears a, dot. the latter are driven I from the shafit 1eadapted to be coupled to the shaft of the armature (if-,the electricgenerator aridthe prime mover p by means of a clutc k. f

In both cases the current is directlyor indirectly supplied t'otheelectromotor or electromotors from the generator 9. The operation of themebhanism is as follows. If the prime mover' is coupled ex'clusively tothe geperator gland the clutch la is thrown out '0 operation, theenergy'supplied from the pr me mover p to the gen-' erator g'is-tra'nsformed into electric energy, and the saidelect ic energy issupplied in an exclusively elec rical'way to the motor m or motors m andm which drive the vehicle and cam-be regulated or reversed in the mannercommonin vehicles of the class described. Q

If the clutch k is constructed as a friction or sliding clutch, thesaidfclutch may used if desired iortransmittingpart'of the energy, sothat the poweris transmitted from the prime mover partly in anelectrical is constructed-ass, friction or sliding clutch,

loit can"be;gradually'lthrown into operation, so' that the vehicle isgradually started, as is 1 necessary because the prime mover can *not'be overcharged'in a large degree. If, however,. the clutch; in isconstructed as an interlocking. clutch, a friction or fsliding' clutchin is preferabl provided "Obviously, the di erent: gearing d isefiective in, both cases, whetn L for starting the vehicle or"-i n thenormal course of'the- Z vehicle.

Glaimsz' f 1.=In driving'mechanism for motor vehicle's, the combinationwith a prime mover and driven members, of a differential gear ingconnectin said prime mover mechanically with sald driven mtinoers, a sinle dynamo connected to be directly driven y said prime mover, and aplurality of electric motors independently connected with and drivingsaid driven members and receiving current 'from said dynamo.
